Thanks for starting this group Frank! Do you have a recommendation for great grilled chicken tacos?

I tried making grilled chicken tacos for the superbowl. While my Carnitas recipe (by Sergio Hernandez...on Cookeatshare) was fantastic, I had to piece together my chicken tacos recipe from a number I saw online. I was looking for the spicy, flavorful, meat that I get at the local taquerias here in San Carlos and Redwood City. I marinated the chicken in heaping tablepoons of cumin and chili powder, liberal salt, lemon juice, and olive oil. It came out good, but not great. Something is missing. If you have a recipe you love or just some ideas, please let me know!
